摘要
以脂肪酸甲酯、乙二胺、氯乙酸钠为原料合成了N-酰基乙二胺二乙酸钠。用单因素优化法研究了影响反应的因素,N-十二酰基乙二胺的优化反应条件为:n(月桂酸甲酯)∶n(甲醇钠)∶n(乙二胺)=1∶0.08∶8,反应温度90℃,反应时间7h;N-十二酰基乙二胺二乙酸钠的优化反应条件为:n(N-十二酰基乙二胺)∶n(氯乙酸钠)=1∶2.5,反应温度75℃,反应时间8h,pH=8～9,收率86.45%。研究表明,N-十二酰基乙二胺二乙酸钠具有良好的表面活性和螯合能力。
Disodium N-acyl ethylenediamine diacetate was synthesized by reactions of methyl laurate, ethylenediamine and sodium chloacetate. With the single factor optimization method to study the in- fluence factors of the reaction, the optimal synthesis conditions for N-lauroyl ethylenediamine were found as follows： n（methyl laurate） ： n（sodium methoxide） ~ n（ethylenediamine） =1 ： 0.08 ： 8, reac- tion temperature 90 ~C and reaction time 7 h. The optimal synthesis conditions for disodium N-lauroyl ethylenediamine diacetate were found as follows： n（N-lauroyl ethylenediamine） ~ n（sodium chloroace- tate）=l ： 2. 5, reaction temperature 75 ~C, reaction time 8 h, and pH=8 - 9, with the yield of 86.45 G. Performance study indicates that disodium N-acyl ethylenediamine diacetate has good surface activity and certain chelating ability.
